Also com- Itis a further object to provide tabs which bined with the roll mountingis a driven endless 50 can be applied to the roll without the exercisebelt 29 which accelerates the replacement roll to of especial care onthe part of the machine opthe speed of the running web, and a brushmemerator. ber 3| which is pivotally mounted at 32 and is With the aboveand other objects in view which adapted to be moved against the runningweb to will appear as the description proceeds, the inmove the said webinto engagement with an ad- 55 hesive portion on the free web end of thereplacement roll to make a web join. Means to sever the web after a joinis made is also indicated at 33.

As soon as the running web adheres to the adhesive portion on thereplacement web end, it is important that the web end is immediatelyfreed from engagement with the body of the roll. This is accomplished byproviding a tab means which is adapted to be secured to both the freeweb end and the body of the roll in a manner which will cause the saidtab structure to be torn or otherwise separated as soon as apredetermined strain is applied thereto such as. by the pulling actionof the web end when the running web engages the adhesive on thereplacement roll.

The tabs herein disclosed may also be used with machines wherein meansare provided for applying adhesive to the running web instead of to theend of the web of the replacement roll.

In Figures 1 and 2, a ring form of tab is shown which has very desirablequalities. In this form, some suitable material such as paper is stampedinto the form of a rectangular ring 34 and has dabs of adhesive 35-35applied to two opposite corners thereof, one corner of which is securedto the body B of the replacement roll at the central portion thereof,while the opposite corner is secured to the web end W of the said roll.An adhesive is also applied along the end of the web as indicated at A,except for a limited space where the accelerating belt 29 will engagethe roll 28.

During the period that the said replacement roll 28 is rotating, thefree end W is adequately held against the body of the roll, but as soonas the running web is brought into contact with the adhesive A on theweb end, the strain exerted upon the tab will tend to pull one end awayfrom the other and will rupture or tear the tab latterly across thecorners, as indicated by the dot and dash lines in Figure 2.

The circular tab structure 36, shown in Figures 3 and 4, is applied inthe same manner as the rectangular ring with one adhesive portion 31engaging the body B of the roll and another adhesive portion 3 engagingthe web end W. When a join is made, the tab is torn along the portionindicated by the dot and dash lines in Figure 4.

When either of the tabs shown in Figures 1 to 4 is used, the action ofpulling the web end away from the roll when it adheres to the runningweb tends to straighten the sides of the ring and thereby stress onlythe inside edges on each side, which quickly starts tears thatimmediately sever the tab.

In Figure 5, another form of tab structure is shown applied to a web endhaving a fish-tail configuration as shown at 38, and in which two tabs39-35? are provided, one at each end of the fish-tail portion. Each ofthe tabs 39-39 is of substantially V-formation and has an adhesive Mapplied over approximately one half of its length on one side and anadhesive 42 applied over approximately one half of its length on theopposite side, as best shown in Figure 6. When securing these tabs inplace, one adhesive portion is secured to the body B of the roll, whilethe other adhesive portion is secured to the web end W, and when. a webjoin is made, the tabs are torn vertically across the central portionsthereof. An adhesive A is also applied to the web end as in thepreviously described structures.

In Figures. '7, 8, and 9, another arrangement is shown wherein a tab 46is formed with a central peak portion having an adhesive 41 on its frontsurface and two end portions 48-48 projecting sideward from said centralportion and having adhesive 49-49 applied on their rear surfaces. Theadhesive ends are secured to the body of the roll and the centraladhesive portion is secured to the free end of the roll, the edge of thesaid free end being shaped to conform with the peak formation of thetab. When a join is made, the tab will be torn along the lines indicatedby the outer boundaries of the adhesive portion 41.

To further assist in the tearing of this form of tab, the ends may beformed so as to project angularly upward as shown at ma-48a in Figures10 and 11, to provide sharp V-shaped portions at 53-50. The adhesiveportions will be applied in the same position as previously describedfor Figures 8 and 9.

It will be observed that in each of the tab structures disclosed, thereare no weak portions in the material structure such as perforations,slits, or the like, but that the full strength of the material structureis maintained throughout the tab.

It will be understood that the invention may be embodied in otherspecific forms without departing from the spirit or essential attributesthereof, and it is therefore desired that the present embodiments beconsidered in all respects as illustrative and not restrictive,reference being had to the claims rather than to the foregoingdescription to indicate the scope of the invention.

What I claim is:

1. A tab member for application to a roll from which a web is to be fedto a machine, formed of material having substantially equal strengththroughout its material structure, one portion having adhesive thereonfor pasting it to the body of the roll and another portion havingadhesive thereon for pasting it to the free end of the web of the roll,in a manner whereby it will hold the free end against the body of theroll even when it is rotated rapidly; said tab member being soconstructed that the said one portion extends from and out of alignmentwith the other portion and is easily separated therefrom at a pointintermediate the portions to release the free end of the web from thebody of the roll when-the said free end is brought into contact with arunning web and adheres thereto.

2. A tab member for application to a roll from which a web is to be fedto a machine, formed of material having its opposite edges parallel andhaving substantially equal cross sectional strength throughout itslength, one portion of said tab member having adhesive thereon forpasting it to the body of the roll and another portion of said tabmember having adhesive thereon for pasting it to the free end of the webof the roll, in a manner whereby said tab will hold the free end againstthe body of the roll even when it is rotated rapidly; said tab memberbeing so constructed that the said one portion extends from and out ofalignment with the other portion and is easily separated therefrom at apoint intermediate the portions to release the free end of the web fromthe body of the roll when the said free end is brought into contact witha running web and adheres thereto.

3. A tab member for application to a roll from which a web is to be fedto a machine, formed of material having its opposite edges parallel, andhaving an equal width and strength throughout its length, one portion ofsaid tab member having an adhesive thereon for pasting it to the body ofthe roll and another portion of said tab member having an adhesivethereon for pasting it to the free end of the web of the roll in amanner whereby it will hold the free end against the body of the rollwhen it is rotated rapidly; said tab member being so constructed thatthe portions are joined by an intermediate integral bent portion and thesaid one portion is easily separated from the said other portion at thebent portion to release the free end of the web from the body of theroll when the said free end is brought into contact with a running weband adheres thereto.
